iPad mount

Has anyone come across a bike mount for an iPad as I'm drawing a blank!

No, I don't want to go cycling the lanes with an iPad strapped to my bars

I have sufferfest videos loaded onto my iPad for watching while I'm on the turbo. At the moment I have it propped on a step ladder in front of my bike but its a little precarious. So I'm after a way to mount the iPad in front of me while I spin myself into a sweaty mess.
